Windows 7: windows 7 refuses to load and system repair wont load

I dont know if this is posted in the right area but I'm so desperate to get my laptop working its unreal.
First it started off with my laptop crashing, I had totally forgot it needed to do a windows update and turned off my laptop in hopes that it would work properly.
After that my laptop has not been working. The machine turns on and gives me two options. Start windows normally or do a repair. Upon starting windows normally, it loads so far before sending me back to the two options of start windows normally or repair. On the second time I clicked repair. My laptop then goes so far before presenting me with a blue screen that is usually the screen where my accounts are. The cursor still moves but it loads no further even after leaving it an hour. I decided to make a repair disk, hoping that the problem was because of windows. the disk loads, gives me a choice on the keyboard language then does nothing. I honestly have no idea what to do, I want to keep all the files safe on my computer as I havent backed them up and I have worked so hard on the projects. someone please help

Do a hardware/software reset with your BIOS:

1. Shut down and turn off the computer.
   
2. Unplug the computer from the wall or surge protector (then remove the battery if it is a laptop).
   
3. "Remove the computer from any port replicator or docking station, disconnect
   cables to printers or devices such as external monitors, USB memory sticks or SD cards, headset or external speakers, mouse or auxiliary keyboard, turn off WIFI and Bluetooth wireless devices." (Use Hard Reset to Resolve Hardware and Software Issues HP Pavilion dv5000 Notebook PC series - HP Customer Care (United States - English))
   
4. Hold down the power button for 30 seconds. This closes the circuit and ensures all
   power from components is drained to clear the software connections between the BIOS
   and hardware and clear any corruption in the temporary memory.
   
5. (If it is a laptop, plug the battery back into the laptop and then) Plug the computer back into the wall. Do not reconnect any unnecessary peripherals; monitor, keyboard,
   and mouse should suffice and be the only peripherals reconnected.
   
6. Turn it on to reinitialize the software connections between the BIOS and hardware
   

After doing those steps, clear your CMOS by entering the BIOS (see your system manual for steps to enter the BIOS), going to the EXIT screen, and loading setup/optimized defaults.
